Could someone explain to me the thinking around making connections using multi-stranded flex? There seem to be plenty of options:
Stripping the end of the flex and just tightening a screw onto it (like in a 13A plug).
Putting an uninsulated bootlace ferrule onto the end using a ratchet ferrule crimper, and then tightening the screw onto it.
Putting an insulated crimped pin terminal on the end with a ratchet crimper, and tightening the screw onto the terminal.
Using an insulated cord end ferrule with a ferrule crimper.
Using an insulated blade terminal with a ratchet crimper.
The reason this has come up is because I'm confident that option 1, just sticking the stripped cable into an immersion heater thermostat and tightening the screw is wrong. I've also ruled out tinning the flex end with solder. But then I am left with a few other options, one of which means I just need to get the right sort of crimp to use with my crimper, and the other means buying a ferrule crimper and crimps.
How do you decide what to do?
